  • A new mater station architecture, based on the open systems concept, has arisen since the IEEE Tutorial, Fundamentals of Supervisory Systems, was written in 1990. The new master station architecture is now widely employed by the industry's vendors and has salient characteristics that can be summarized as follows: Industry standard hardware is used to the greatest extent practical; Industry standard software is used to the greatest extent practical; A network of computers is accepted as the basic paradigm; Configurations exploiting the above characteristics are favored; Configurations based on proprietary hardware are avoided. An illustration of a system following the newmore » master station architecture is provided. This article explains why the change occurred, details major characteristics of the new architecture, and speculates on the effects the new architecture will have on the three major industry participants: utilities (buyers) purchasing the systems, contractors (sellers) building the systems, and consultants assisting in system procurement.« less
  • The 1950s and 1960s were characterized by the development and introduction of instrumental procedures for analysis. UKhIN developed photocolorimetric procedures for monitoring the performance of sulfur removal and dephenolization equipment, determining the HCN contents of gases, determining nitrous oxide in gas for synthesis and determining polysulfide sulfur in the absorbent solutions from sodium thiocyanate equipment. The GOST standard on benzene hydrocarbons was supplemented by photocolorimetric procedures for determining the color indices of sulfuric acid, carbon disulfide and thiophen. Potentiometric procedures are used for the quality control of absorbent solutions in sulfur removal and sodium thiocyanate sections and rapid procedures havemore » been proposed for the analysis of pyridine bases, phenolates and ammonium sulfate acidity. The development and introduction of the complexometric procedure gave speedier and more accurate results in the determination of ferrocyanides, sulfates, and total sulfur contents in absorbent solutions used in sulfur-removal shops and sodium thiocyanate sections. The analytical standards for product quality monitoring and process control were significantly raised by the introduction of gas chromatography, in 1960 to insestigate and develop the catalytic hydrorefining of crude benzol fractions. The range of applications for chromatographic separation has subsequently widened, from the examination of complex mixtures of various classes of coke-oven products boiling up to 520/sup 0/C, using capillary columns 0.25 mm in diameter, to the commercial preparation of pure substancs in columns up to 200 mm in diameter. UKhIN efforts to standardize the terminology, procedures and methods of chromatography enabled research and plant workers to evolve a uniform technical language and a common procedural approach to chromatographic analysis.« less
  • Plant-insect interactions can alter ecosystem processes, especially if the insects modify plant architecture, quality, or the quantity of leaf litter inputs. In this study, we investigated the interactions between the gall midge Rhopalomyia solidaginis and tall goldenrod, Solidago altissima, to quantify the degree to which the midge alters plant architecture and how the galls affect rates of litter decomposition and nutrient release in an old-field ecosystem. R. solidaginis commonly leads to the formation of a distinct apical rosette gall on S. altissima and approximately 15% of the ramets in a S. altissima patch were galled (range: 3-34%). Aboveground biomass ofmore » galled ramets was 60% higher and the leaf area density was four times greater on galled leaf tissue relative to the portions of the plant that were not affected by the gall. Overall decomposition rate constants did not differ between galled and ungalled leaf litter. However, leaf-litter mass loss was lower in galled litter relative to ungalled litter, which was likely driven by modest differences in initial litter chemistry; this effect diminished after 12 weeks of decomposition in the field. The proportion of N remaining was always higher in galled litter than in ungalled litter at each collection date indicating differential release of nitrogen in galled leaf litter. Several studies have shown that plant-insect interactions on woody species can alter ecosystem processes by affecting the quality or quantity of litter inputs. Our results illustrate how plant-insect interactions in an herbaceous species can affect ecosystem processes by altering the quality and quantity of litter inputs. Given that S. altissima dominates fields and roadsides and that R. solidaginis galls are highly abundant throughout eastern North America, these interactions are likely to be important for both the structure and function of old-field ecosystems.« less
  • In this paper, a novel distributed hierarchical coordinated control architecture is proposed for large scale power systems. The newly considered architecture facilitates frequency restoration and power balancing functions to be decoupled and implemented at different levels. At the local level, decentralized robust generator controllers are designed to quickly restore frequency after large faults and disturbances in the system. The controllers presented herein are shown to improve transient stability performance, as compared to conventional governor and excitation control. At the area level, Automatic Generation Control (AGC) is modified and coordinates with the decentralized robust controllers to reach the interchange schedule inmore » the tie lines. The interaction of local and zonal controllers is validated through detailed simulations.« less
